Power steering issues

[buffblazer]

Installed a cooler on my 86 k5. I filled the pump and started it and it was growling, then I noticed it was pushing fluid out thru the inlet side of the box. So thinking there was air in the system I cracked the outlet side and fluid started coming out of there but also continued to come out of the inlet side.

The growling went away after I opened the outlet side but why is it still pushing it out of the inlet?

I still have not been able to tell if it's even pushing fluid into the cooler yet or if it's even returning it to the pump

Did you bleed the system?

 

[Fordum]

Were there any plugs in the fittings of the cooler, and are you sure you got them out?

I left the cap off and cracked that line to bleed it and the only 2 caps on the cooler were on the ends for the hoses and I took them off

Ok so after dumping a gal of fluid on the ground it's still pushing fluid out thru the inlet line of the box. It's not going thru the threads but in-between the nut and the line.

I have bled it the best I can and it's still pushing fluid and I also still don't have P/S

Its late, and I need to be in bed, but something about this just strikes me as wrong.

You say fluid is coming out of the inlet line between the nut and line.
OK, there should not be any pressure to speak of there.
The pressure comes out the output line, goes through the system, and just dumps back into the pump.
Either the O ring is complely gone, or there is a restriction at the inlet.
That fitting is not supposed to have to withstand high pressure, but if the inlet to the pump was blocked some way, then the pressure from the outlet would have no where to go and would force its way out there.

Either a hose is hooked up wrong somewhere, or there is a blockage at the input. Pull that fitting off and see if there is something in the hole in the pump, or the line.

Sometime they changed from a flare line to an iso style line, do you have the wrong lines or possibly the wrong year box? The fittings can be changed on the pump to accommodate what you need

Is there an O ring that goes down inside the hole? Or is it just up to that nipple end to seal it?
